wireless telecommunications, Roaming helps to make sure that a travelling wireless device, typically a mobile phone, is kept connected to a network, without breaking the connection.<\/p>\n<p>For example, if you travel beyond your mobile phone company\u2019s transmitter range, your mobile will automatically \u201chop on to\u201d another phone company\u2019s service, where it is available.<\/p>\n<div style=\"height: 2em;\"><\/div>\n<h4>Who is Roaming valuable for?<\/h4>\n<ul>\n<li>Operators<\/li>\n<li>Consumers<\/li>\n<\/ul>\n<div style=\"height: 2em;\"><\/div>\n<h4>What are
